Fix PR6497, a bug where we'd fold a load into an addc
node which has a flag. That flag in turn was used by an
already-selected adde which turned into an ADC32ri8 which
used a selected load which was chained to the load we
folded. This flag use caused us to form a cycle. Fix
this by not ignoring chains in IsLegalToFold even in
cases where the isel thinks it can.

Teach lit to honor conditional directives. The syntax is:
IF(condition(value)):
If the value satisfies the condition, the line is processed by lit; otherwise
it is skipped. A test with no unignored directives is resolved as Unsupported.
The test suite is responsible for defining conditions; conditions are unary
functions over strings. I've defined two conditions in the LLVM test suite,
TARGET (with values like those in TARGETS_TO_BUILD) and BINDING (with values
like those in llvm_bindings). So for example you can write:
IF(BINDING(ocaml)): RUN: %blah %s -o -
and the RUN line will only execute if LLVM was configured with the ocaml
bindings.
